Background
- Gram-negative bacillus
- Acquired from unpasteurized milk, undercooked meat (especially pork), contaminated water
- Classic association with chitterlings
Clinical Manifestations
- Incubation period of Usual incubation period:1 to 14 days
- Gastroenteritis, often with pain isolated to right lower quadrant mimicking appendicitis
- Concurrent pharyngitis in 20%, can can be isolated from throat swabs
- Complications include hematogenous dissemination with metastatic abscesses in the liver and spleen, mesenteric adenitis, terminal ileitis, and pseudoappendicitis
- Can lead to reactive arthritis and erythema nodosum
Management
- Unclear if antimicrobial treatment is beneficial unless severe
- Generally indicated in:
- Severe disease
- Extraintestinal disease, including meningitis, cellulitis, pneumonia, osteomyelitis, and endocarditis
- High risk populations, including the elderly, people with diabetes, people with cirrhosis, and immunocompromised patients
- Options include ciprofloxacin, ceftriaxone, TMP-SMX, doxycycline, and aminoglycosides
